Grove was able to pull the otter off of Bryce, but not before suffering multiple injuries herself.

“It just started biting on me and biting on me and it felt like little knives just going in,” Grove told the station.

Both Grove and Bryce were taken to a hospital where Grove reportedly received hundreds of stitches to her face and head and Bryce received nine staples in his head. Grove also suffered an injury to her right eye, which may result in minor long-term damage. The two were released Friday night.

The Washington State Department of Fish and Wildlife says the incident is a unique case.

“When they do happen, they’re usually a female with pups,” said Bartlett, who explained that the otter likely attacked after noticing Bryce too close to her pups. Such attacks usually happen in July and August, when the otters have their pups with them.

Bartlett said that officers located a female otter with pups on Tuesday, and that efforts to trap and relocate the otter and her pups are currently underway.

Grove and Bryce continue to recover at home, KOMO News reports. Though the attack has caused much physical injury, Grove maintains that she would do it all again if it meant protecting her grandson.

Lelani Grove could not be immediately reached by ABC News for comment.
